TECHNICAL FIELD

[0001] The utility model relates to the technical field of woven bag production, in particular to a split type mould for a cast iron machine. BACKGROUND

[0002] In modern industrial production, as a common packaging material, the quality and performance of woven bags depend largely on the pretreatment effect of raw materials. With the continuous improvement of the quality requirements of woven bags, the traditional raw material processing method gradually exposes some problems. In the past, the screening, cleaning, drying and crushing of raw materials often adopted a relatively simple and extensive way.

[0003] However, the screening process may not be fine enough, resulting in impurities remaining, which can affect the physical properties of woven bags such as strength, toughness and wear resistance. Larger impurities may block the feed inlet, mould or channel of subsequent processing equipment, causing production interruption, which requires time for cleaning and maintenance, thereby reducing the overall production efficiency.
